Interested in a similar setup to this but on stock suspension. Do you think think the additional negative camber and fender rolling would still be needed if on stock suspension? Thanks! Quote:

As you can see later on in that thread myself and others went with 17x8.5 instead but every once in a while I wonder if I could've pulled it off. For me it wasn't worth the risk.

So an ec7 pop up locally in the following specs.
18x8.5 et 45 front w/ 225/40 18 18x9.5 et 58 rear w/ 265/35 18 tires ps4s I read through this forum and apex fitment guide and found that it might be a good fit with 5mm spacers front and back. Question is, would this setup still fit if my m240i is lowered on dinan spring? |

I have the 18X8.5” ET35 EC-7s up front with DINAN lowering springs (1/2”) and camber plates.
Would a 235 40 RE-71RS fit? I see that people run that size in other brands, but the 71s are a big tire. 8.5 inch tread width vs 7.8 for a PS4S of that size. I would rather not run a ton of negative camber on the street because of tire wear, but have the option to dial in the camber plates. Would I get better handling with that size vs a 225 RE 71? It is also large at a 7.9 tread width. Plan to run 255 in the rear. |

Where is the first place I would rub on the fender side so that I can get a good measurement with my existing tires? Is it going to be the metal fender at the top? |

This is a set of the older RE-71R tires that one of our employees destroyed on track with the stock alignment on his 228i: (sorry Jake) If your front tires were to contact the fenders, it would likely be the inner lip of the metal fenders. If you're trying to see if they rub but don't hear audible rubbing, you can rub some chalk on the inner edge of the fender or liner and go for a drive where you get suspension compression as long as it's dry out. -Tom

Thanks Tom. I have about 1.8 negative camber dialed in for the street and would go up to about 3.0 for track days.
I’m a little torn what to do. If I run the 225 RE71 instead to guarantee no rub, then the 255 in back may promote under steer. Unfortunately they don’t make a 245, so the next size down would be a 235 in the rear. I may get the tire shop to try the 235 up front and if it rubs,throw that in the rear and go with the 225 up front. That would probably give me more balanced handling? |

I have a set of 17x8.5 ET40 ARC-8 wheels coming soon for a square setup. Has anybody tried 245/40/17 all-seasons on stock suspension?
TireRack shows the section width as followed: Michelin Pilot Sport 4S: 9.8" Michelin Pilot Sport All Season 4: 9.9" Continental ExtremeContact DWS Plus 06: 9.8" I may be over-stressing how tight this fitment is, but just want to make sure I won't have any issues! |

Tires are 245/40-17 RE-71R (old model). I don't have measurements from TR for these older tires, but the new RE-71RS is 9.8" in section width and 8.4" in tread width for this size. I'd pay attention to tread width as much if not more than section width as the tread width is measuring the tire at the point that is most likely to contact the fenders in most cases. This setup was a direct fit on this car in terms of tires, and he was on the stock alignment, but if you have the larger 345mm rear brakes, any 17" ARC-8 fitment is going to scratch up the caliper/pad vibration damping "ears" /the barrel of the wheel. -Tom

Thanks! I had only seen in this thread Kinesthesia and Cos270 running PS4S's. I've seen your build thread (great build!) and knew that you went with these wheels, too, but I must have overlooked the fact that you were on AS4's. |

Hey All,
I've been playing catchup this week and haven't had time to build out the true commercial and Sprint-line thread you guys deserve. That will be coming next week BUT.... I wanted to give you a quick heads-up before we went into the weekend. After quite a bit of development time and back and forth on these wheels, we are releasing VS-5RS forged wheels for the 2 series. The fitments are going to be 18x8.5 ET40 front, and 18x9.5 ET58 rear. This is a familiar combination to many and should actually work better on the 2 series than many of our past fitments. The 18x8.5 ET40 can also of course be run square. Many of you have already seen this car on 17" wheels, but here's a taste of the design on this chassis in a smaller diameter: 17x9 ET42 square shown above Pledging for the 18" Group Buy is open and includes these wheels and the Fitment Guide is updated. The wheels are arriving in May. While we weren't initially going to include them in the Group Buy, we wanted to give the 2 series community the opportunity to join the Ongoing deal and lock in a discount on these wheels, especially those of you who have been waiting since our original release. I hope you enjoy these wheels and are as excited about them as I am. I'll have more news and content around these fitments in the future but let me know if you have questions about these wheels and I'll dive into them next week. -Tom

Hello! And thank you for this site☺️
help please choose the right size for my m240xi I have original suspension and H&r springs I’ve been struggling to choose for a week I want to buy APEX ARC-8 My rubber Michelin pilot sport 5 225/40 and 255/35 R18 already bought Option 1 Front R18 8.5 et45 225/40 r18 (as I understand at 225 no spacer needed) Rear R18 8.5 et45 255/35 r18 Will there be any problems with the rear wheels? Blows on the wing outside and rub? With the civil collapse of the Convergence and without a big negative angle? I’m afraid of it and I really hope you think about it Option 2 Front 18 8.5 et38 225/40 Rear 18 8.5 et45 255/35 Option 3 Front 18 8.5 et45 225/40 without spacer is good? Rear 18 9.5 et58 255/35 without spacers Help please sort out and buy the most faithful kit for my 240 with h&r springs without hitting the wing and friction Thank you |

With a square setup, you have the ability to rotate your wheels/tires to maximize tread life, while gaining a more neutral handling balance with fewer understeer characteristics compared to a staggered setup. The main benefit of a staggered setup is being able to run a wider rear wheel/tire, which is beneficial on a RWD car but not so much on an Xdrive car. With that said, if you have already purchased staggered tire sizes with a 225/40-18 front and 255/35-18 rear, I would recommend using the following ARC-8 wheels for the best results: Front: 18x8.5" ET38 W/ 225/40-18 tires Rear: 18x9.5" ET58 W/ 255/35-18 tires This setup will be a complete direct fit on a H&R lowered 2-Series and will not require any additional modifications to fit. If you would like to check out some of our other 2-Series offerings, our chassis specific fitment guide can be found here: https://support.apexraceparts.com/hc...-Fitment-Guide If you have any additional questions, please let me know. -Geirsen

Tough one to answer honestly. There is no easy way to do it without modifications or compromise in some way. I'd take a look at our guide for some recommendations. Each setup is going to require some adjustments for 255s.
It's going to be very tire dependant as well. Tires' actual real-world measurements aren't always fully reflected in the sizes so while I could probably recommend setups that are going to easily run 255/35-18 all seasons, if someone then turned around and ran the same-sized tire in RT660 or some other extreme performance summer they'd rub like crazy. With some mods you probably could ie front camber. I usually recommend running a shorter sidewall with the 245s though as a 245/35-18 is going to reduce your chances of rubbing both under compression and when turning lock to lock up front. Quote:
265/35-18 will be a direct fit in the rear, but I’d only recommend running that wider rear tire if you also went to the wider front to prevent excessive understeer. -Tom
